Hi,

rqt_reconfigure looks working badly on my computer. It shows a totally empty window. It is showing no parameter, no grid, and no command window. Nothing.
I was trying to reconfigure the parameter of the pointgray camera. Cutting off Auto exposure and Turn on the Trigger.
I tried troubleshooting in the rqt_reconfigure wiki but it seems there is no problem. There are some return by hitting "$ rosrun dynamic_reconfigure dynparam list".
Below is a screenshot of troubleshooting(left) and rqt_reconfigure window(right). Does anyone have a solution to this?

Thank you in advance.

Hi,

I am trying to create some widgets for RobotWebTools to monitor/control my robot on the Web browser remotely. According to the nav2djs(one of the widgets of the RobotWebTools) tutorial, the HTML code was shown. So, I decided to use this code as a Base and modify for my original. The code includes the line as below.
My robot and other equipment such as laptop and tablet are all connected in the same Network. However, it is not connected to the Internet. It means all ".js" files cannot import from http://cdn~~~ .
I sought for each JS file in order to download and place at the same directory as the HTML file. However, I couldn't find most of those. Does anyone have some solution of this?

Thank you in advance.

Hi all,

I am using the LMS1xx pkg to obtain laser measurements from a sick LMS-151 laser. The pkg works good at 50 Hz frequency. However, if I change it to 25 Hz by SOPAS ET, message never comes out. Also, "stop" lamp and "OK" lamp on the laser it self alternately flashes.

I found below from the source code.

if (cfg.scaningFrequency != 5000)
{  
    laser.disconnect();  
    ROS_WARN("Unable to get laser output range. Retrying.");  
    ros::Duration(1).sleep();   continue;
}

I thought this is the reason why it does not work good at 25 Hz. So, I changed 5000 to 2500. However, now the program stopped by some kind of memory Error.

Does any one have an idea to solve this problem?

Best

Yoshi

UPDATE 7/19/18
The source I am using is this.Thanks to tonybaltovski.
https://github.com/clearpathrobotics/...
The reason why I use source code instead of apt-get was to change range_max from 20.0 to 50.0 and to change angle resolution from 0.5 deg to 0.25 deg. This problem is for the latter.

The memory error which I wrote above disappeared once I restarted the computer. Sorry for the confusing information. It won't stop with error, just publishing no message forever.

I checked the sensor with SOPAS which is SICK software. There are some Monitor system and it looks no problem in both 50Hz and 25Hz. The lamp on the sensor was lighting up only "OK" continuously at that time. Also, "STOP" lamp never flashes while I read the message beyond ROS at 50Hz.

Thank you
